<ul>
    <li><b>Atom & Bond labels</b> are used as the default font type and size to labels
        such as C/T label of bonds, atom query property labels of atoms, etc.</li>
    <li><b>Double bond spacing</b> is a gap between two lines/sticks representing a double or triple bond measured in Angstroms.</li>
    <li><b>Wireframe bond thickness</b> is the width of bonds in wireframe mode. It is measured in Angstroms.</li>
    <li><b>Stick diameter</b> is the width of bonds in stick mode in Angstroms.</li>
    <li><b>Ball radius</b> is the size of atom spheres in Ball draw type, measured in Angstroms.</li>
    <li><b>Look & Feel</b> allows changing the visual appearance of GUI components.
        The available options are: Java Metal, Motif, JGoodies Plastic, JGoodies Plastic XP,
        and the native Look & Feels (Windows, Aqua) based on the underlying operating system.</li>
    <li><b>Show Bond in Hand</b> when checked bond types are shown under the mouse cursor like template structures.</li>

        <li><b>Any Bond Line Style</b> offers three different modes to display bonds of unkown types: Automatic, Dashed and Solid.
        This option can be separately set to be used in MarvinSketch and MarvinView.</li>

                <li><b>Unbalanced Reactions</b> highlights stoichiometrically wrong reactions with red rectangle around reaction arrows when this option is checked.</li>
            </ul>-->

<h4>Save/Load</h4>
    <img src="../../sketch/gui/gui-files/dialogs/preferences4.png" width="477" height="284"><br>
    <ul>
        <li><b>Default location:</b> the folder from which to load or to save molecules may be set by the user.
        <ul><li>Startup directory: the folder where the command to start the application was given.</li>
            <li>Last location: the last folder used for opening or saving a structure.</li>
            <li>Custom working directory: a user-defined folder. If
            a molecule is loaded from another folder, then the file's location will be offered for saving.</li></ul>
        </li>
        <li><b>Default file format</b> determines which type is offered by default when structures are saved to file.</li>
        <li><b>Save/Load settings</b>
            <ul><li><b>Save GUI settings to MRV</b> allows storing parameters like background color,
            font type, etc. beside the structures. This option can only be used with the
            <a href="../../formats/mrv-doc.html">MRV format</a>.</li>
        <li><b>Load GUI settings from MRV</b> restores parameters like background color,
            font type, etc. when this information is present beside the structures.
        This option can only be used with the <a href="../../formats/mrv-doc.html">MRV format</a>.</li></ul>
        </li>
    </ul>
<h4>Copy</h4>

    <ul>
    <li><b>Copy molecule as</b><br>
    This panel offers additional formats in which structure data can be put to clipboard.
    This can be useful for example when you wish to insert the image of the molecule to
    an image editor application, which would not recognize the input data without enabling image formats.<br>
